This is the core Go component of the DataSketches library. It contains some of the sketching algorithms and can be accessed directly from user applications.
Note that we have a parallel core component for C++, Java and Python implementations of the same sketch algorithms, datasketches-cpp and datasketches-java.
Please visit the main DataSketches website for more information.
